Soil Mercury And Its Response To Atmospheric Mercury Deposition Across The Northeastern United States, Xue Yu, Charles T. Driscoll, Richard A. F. Warby, Mario Montesdeoca, Chris E. Johnson

Civil and Environmental Engineering - All Scholarship

Terrestrial soil is a large reservoir of atmospherically deposited mercury (Hg). However, few studies have evaluated the accumulation of Hg in terrestrial ecosystems in the northeastern United States, a region which is sensitive to atmospheric Hg deposition. We characterized Hg and organic matter in soil profiles from 139 sampling sites for five subregions across the northeastern United States and estimated atmospheric Hg deposition to these sites by combining numerical modeling with experimental data from the literature. We did not observe any significant relationships between current net atmospheric Hg deposition and soil Hg concentrations or pools, even though soils are a …

Effective Strategies For Increasing Citation Frequency, N. Ale Ebrahim, H. Salehi, M.A. Embi, F. Habibi Tanha, H. Gholizadeh, S.M. Motahar, A. Ordi

Research Publications (2011 to 2015)

Due to the effect of citation impact on The Higher Education (THE) world university ranking system, most of the researchers are looking for some helpful techniques to increase their citation record. This paper by reviewing the relevant articles extracts 33 different ways for increasing the citations possibilities. The results show that the article visibility has tended to receive more download and citations. This is probably the first study to collect over 30 different ways to improve the citation record. Further study is needed to explore and expand these techniques in specific fields of study in order to make the results …

At its best, a university is a collection of individuals ‐‐ students and faculty ‐‐ focused on learning and discovering new knowledge. For this goal to be realized, a critical element is having faculty members deeply engaged with their disciplines. Scholarship, in the form of journal articles, book chapters, monographs and similar endeavors, creative activity which can take an even wider range of forms, and funded research which explores the boundaries of their disciplines all contribute to such engagement. Through such participation, faculty members stay at the growing edges of their fields, and in so doing, they enrich their intellectual …

The Cultural Whys Of Mental Retardation: Etiologies Among The Asante In Ghana, West Africa, Chelsea Shields, Dr. William C. Olsen

Journal of Undergraduate Research

During my time as an international student at the University of Ghana and volunteering at a school for mentally handicapped children, I uncovered a large lacuna in non-western mental retardation research and decided to return the next year as BYU’s Ghana Medical Anthropology field study facilitator. I desired to document and disclose Asante beliefs behind mental retardation under the hope that such awareness would lead to more positive treatment of handicapped individuals.

Engineered Nanotopography On Electrospun Plla Microfibers Modifies Raw 264.7 Cell Response, Nicholas J. Schaub, Tara Britton, Rupak Rajachar, Ryan J. Gilbert

Chemical and Biochemical Engineering Faculty Research & Creative Works

In this study, we created a new method of electrospinning capable of controlling the surface structure of individual fibers (fiber nano topography). The nano topographical features were created by a phase separation in the fibers as they formed. To control the phase separation, a nonsolvent (a chemical insoluble with the polymer) was added to an electrospinning solution containing poly-l-lactic acid (PLLA) and chloroform. The nano topography of electro spun fibers in the PLLA/chloroform solution was smooth. However, adding a small weight (< 2% of total solution) of a single nonsolvent (water, ethanol, or dimethyl sulfoxide) generated nanoscale depressions on the surface of the fibers unique to the nonsolvent added. Additionally, nanoscale depressions on electro spun fibers were observed to change with dimethyl sulfoxide (DMSO) concentration in the PLLA/chloroform solution. A nonlinear relationship was found between the concentration of DMSO and the number and size of nano topographical features. The surface depressions did not alter the hydrophobicity of the scaffold or degradation of the scaffold over a two-day period. To determine if fiber nano topography altered cell behavior, macrophages (RAW 264.7 cells) were cultured on fibers with a smooth nano topography or fibers with nanoscale depressions. RAW 264.7 cells spread less on fibers with nanoscale depressions than fibers with a smooth topography (p < 0.05), but there were no differences between groups with regard to cell metabolism or the number of adherent cells. The results of this study demonstrate the necessity to consider the nano topography of individual fibers as these features may affect cellular behavior. More importantly, we demonstrate a versatile method of controlling electro spun fiber nano topography. © 2013 American Chemical Society.

Word Sense Disambiguation Through Analogical Modeling, Deryl Keith Hatch, Dr. Deryle Lonsdale

Journal of Undergraduate Research

In the early twentieth century, throngs of male Greek immigrants came to Utah. They left their homeland seeking to save their families from impending poverty and to escape draft by the Greek and Turkish armies.1 The jobs they took in Utah mines, smelters, and rail yards were lowpaying and dangerous, but these were the least of the troubles waiting for Greeks in Utah. They found Mormons and other Utah residents to be inhospitable and strange, and they quickly learned to isolate themselves in all-Greek communities.

The Sophie Digital Library Of Early Women’S Research: A Blueprint For Mentored Undergraduate Online Research, Blaine Evanson, Dr. Michelle Stott James

Journal of Undergraduate Research

I was first introduced to Sophie in September 2001 in my German Cultural History class. Dr. McFarland announced that there was some grant money left over and that some students who were interested in the research would be invited to work a few hours each week helping prepare texts to be published on the website. I immediately recognized the opportunity to get research experience and knew both how important and beneficial such an opportunity would be, as I was planning on applying the following year for graduate school.

Openness In International Adoptions: An Idea Whose Time Has Come? The Experience Of U.S. Families Who Adopted Children From The Marshall Islands, Jamie Wyatt, Jini Roby

Journal of Undergraduate Research

Increased globalization of today’s society is bringing about dramatic change; the social sciences are not exempt from the results of these changes. Particular to this research study is the issue of international adoptions, particularly those which are characterized as open. “Open adoption” was defined in this study to be some form of continued contact between the biological and adoptive families following the finalization of an adoption. International adoptions are a relatively new concept in and of themselves; international adoption compounded with openness was largely unheard of until the recent onset of globalization when open adoptions increased in accessibility and desirability …

Tunable Cytotoxicity Of Rhodamine 6g Via Anion Variations, Paul K.S. Magut, Susmita Das, Vivian E. Fernand, Jack Losso, Karen Mcdonough, Brittni M. Naylor, Sita Aggarwal, Isiah M. Warner

Faculty Publications

Chemotherapeutic agents with low toxicity to normal tissues are a major goal in cancer research. In this regard, the therapeutic activities of cationic dyes, such as rhodamine 6G, toward cancer cells have been studied for decades with observed toxicities toward normal and cancer cells. Herein, we report rhodamine 6G-based organic salts with varying counteranions that are stable under physiological conditions, display excellent fluorescence photostability, and more importantly have tunable chemotherapeutic properties. Our in vitro studies indicate that the hydrophobic compounds of this series allow production of nanoparticles which are nontoxic to normal cells and toxic to cancer cells. Furthermore, the …

KIP Articles

The ancestor of Gloeobacter violaceus PCC 7421T is believed to have diverged from that of all known cyanobacteria before the evolution of thylakoid membranes and plant plastids. The long and largely independent evolutionary history of G. violaceus presents an organism retaining ancestral features of early oxygenic photoautotrophs, and in whom cyanobacteria evolution can be investigated. No other Gloeobacter species has been described since the genus was established in 1974 (Rippka et al., Arch Microbiol 100:435). Gloeobacter affiliated ribosomal gene sequences have been reported in environmental DNA libraries, but only the type strain's genome has been sequenced. However, we report here …

Udp-Glucose Dehydrogenase Activity And Optimal Downstream Cellular Function Require Dynamic Reorganization At The Dimer-Dimer Subunit Interfaces, Annastasia S. Hyde, Ashley M. Thelen, Joseph J. Barycki, Melanie A. Simpson

Department of Biochemistry: Faculty Publications

Background: UDP-glucose dehydrogenase (UGDH) mutants were engineered to perturb hexamer:dimer quaternary structure equilibrium.

Results: Dimeric species of UGDH have reduced activity in vitro and in supporting hyaluronan production by cultured cells.

Conclusion: Only dynamic UGDH hexamers support robust cellular function.

Significance: Manipulation of UGDH activity by hexamer stabilization may offer new therapeutic options in cancer and other pathologies.

SUMMARY
UDP-glucose dehydrogenase (UGDH) provides precursors for steroid elimination, hyaluronan production, and glycosaminoglycan synthesis. The wild-type UGDH enzyme purifies in a hexamer-dimer equilibrium, and transiently undergoes dynamic motion that exposes the dimer-dimer interface during catalysis. In the current study, we created …

Rapd Analysis Of Three Breeding Lines In Horses, Gregory B. Tilton, Dr. Robert L. Park, Jerran Flinders

Journal of Undergraduate Research

The focus of this project was two-fold. First, to test whether RAPDS, a genetic marker finding technique, could be used to find markers in three separate sire/offspring groups of horses. Second, to determine whether we could use RAPDs to produce a similarity index indicating how genetically related the different groups were to each other, a process that may be valuable in a future genetic study of horse gait. We used the DNA from three horse sires and seven of their offspring, giving a total of twenty-four different horses. The individuals, all of which are registered Missouri Foxtrotters, are located on …

Structure And Dimensions Of Maternal Perceptions Of Japanese And American Child Temperament, Kenichi Shimokawa, Dr. David Shwalb

Journal of Undergraduate Research

The study of temperament has an important part in furthering our understanding about human development. Although the word “temperament” is defined in various ways by researchers, two leading theorists defined it as “constitutionally based individual differences in emotional, motor, and attentional reactivity and self-regulation” (Rothbart & Bates, 1997, p. 108). This definition, particularly, the term “constitutional” emphasizes the biological aspect of temperament. However, Dr. Shwalb and other researchers found evidences that suggest the influence of culture on how people perceive others temperament. Specifically, we studied the differences between maternal perceptions of Japanese and American child temperament to better understand how …

Effects Of Weak Transcranial Alternating Current Stimulation On Brain Activity—A Review Of Known Mechanisms From Animal Studies, Davide Reato, Asif Rahman, Marom Bikson, Lucas C. Parra

Publications and Research

Rhythmic neuronal activity is ubiquitous in the human brain. These rhythms originate from a variety of different network mechanisms, which give rise to a wide-ranging spectrum of oscillation frequencies. In the last few years an increasing number of clinical research studies have explored transcranial alternating current stimulation (tACS) with weak current as a tool for affecting brain function. The premise of these interventions is that tACS will interact with ongoing brain oscillations. However, the exact mechanisms by which weak currents could affect neuronal oscillations at different frequency bands are not well known and this, in turn, limits the rational optimization …
